So I use my MacBook for photo editing on Aperture 3 (Version 3.2.4), I can't actually upgrade it anymore since newer versions require at least Lion. Since I have an Early 2008 MacBook, I can't upgrade to Mountain Lion, which sucks but isn't the end of the world. Now I was wondering if it was worth it to upgrade to Lion to get the updates for Aperture 3. Do the updates my Aperture 3 perform better? Also I hear a lot of bad reviews about how Lion is pretty slow, so at the moment I'm not sure. My Early 2008 Macbook 2.1 GHz Intel Core2Duo, currently has the 120 GB Hard drive it came with. I now have 2.5 GBs of RAM now. What do you guys thing?
